Error: no such table when extending Abstract User Model-CodePudding

I wanted to extend the Base Abstract User Model within Django to have some other Fields:

class Student(AbstractUser):
    birth = models.DateField(default=datetime.date.today)
    street = models.CharField(max_length=20)
    street_number = models.IntegerField(validators=[MinValueValidator(0), MaxValueValidator(99)])
    city = models.CharField(max_length=20)
    province = models.CharField(max_length=20)
    code = models.IntegerField(validators=[MinValueValidator(0, MaxValueValidator(9999))])
    address = str(street)   str(street_number)   str(city)   str(code)   str(province)

    def __str__(self):
        return f'Adresse: {self.address}'

I added this into my settings.py file:

AUTH_USER_MODEL = 'mainApp.Student'

But I get an Error saying there is no such table "Student" when trying to load /admin/. I have made all the migrations using:

python manage.py makemigrations mainApp
python manage.py migrate mainApp

Error:

OperationalError at /admin/

no such table: mainApp_student

If y'all need any more infos, please comment!

CodePudding user response：

Try in first time to run:

python manage.py makemigrations
python manage.py migrate

Without put the app name to migration process

CodePudding user response：

You cannot define "address" like this. Database column is not for string concatenation of other columns, nor any calculation. It can cause error.
